If, at the end of an installation there is an infinite wait on "Windows Installer Coordinator", you are trying install VBA (chained MSI) on a Domain Controler running an OS Server where RDS is configured.
There is a workaround:
It is necessary to modify the Group Policy for the "Windows Installer RDS Compatibility"
The way described below concerns a Windows Server 2012, I think there is a similar way on previous Server systems.
How to proceed (on Windows Server 2012)
1) Log on to the system with a User that has Administrative Privileges
2) Open the Windows Control Panel
3) Perform a search for Group Policy
4) The search results should display a link to the "Local Group Policy Editor"
5) Once inside the editor, go to: Computer Configuration->Administrative Templates->Windows Components->Remote Desktop Services->Remote Desktop Session Host->Application Compatibility
6) In the right pane, right click on 'Turn off Windows Installer RDS Compatibility" and select Edit from the drop down menu
7) Select the Radio Button labeled 'Enable'
8) Click OK
You can also use one of the following versions (or later)
• PcVue 10.0 SP1 Update : 10.0.16054
• PcVue 10.0 SP2 : 10.0.20033
• PcVue 11 Update : 11.0.06007
• PcVue Later (11.1 & 12) : from the 1st production
• FrontVue 5.0 SP1 Update : 5.0.16001
• FrontVue 5.0 SP2 : 5.0.20001
• FrontVue 11 Update : 11.0.06001
• FrontVue Later (11.1 & 12) : from the 1st production
Note:
- If your computer runs an OS Server, but is not Domain Controler, any installation works well.
- If VBA is already installed on your computer, any installation works well.
